Unable to correctly import framework into xcode project

I'm trying to add KKGridView to my project. I've followed thier description from github as best I can:

Create a new workspace in Xcode in the same directory as your existing *.xcodeproj.
Drag in your existing Xcode project
Locate your copy of KKGridView, drag KKGridView.xcodeproj into the workspace so that it stays at the top of the hierarchy, just like your original project.
In the Build Phases section of your original project, link your project with libKKGridView.a.
Now, simply import KKGridView just like an Apple framework:

But libKKGridView appears in red in my project, and I am unable to import any of the code with

#import <KKGridView/KKGridView.h>

enter image description here

Any ideas?

Solution

Copy this file physically to your folder,and then add file to xcode from there.Drag and drop create this problem sometimes. Hope this helps you.
